(eras-var 1 Claim.

This invention appertains to new and useful improvements in linkedstructures such as can be ornamentally and usefully adapted to theconstruction of bracelets.

The principal object of the present invention is to provide a structureof the character stated in which the various interconnected elements canbe removed or others added to decrease or increase the size of theassembly.

Other objects and advantages of the invention will become apparent tothe reader of the following specification.

In the drawing:

Figure 1 representsa side elevational view of a cluster ofinterconnected links.

Figure 2 is an edge elevational view of the structure shown in Figure 1.

Figure 3 is an inside elevational view of one of thelinks.

Figure 4 is an inside eievational view of a link comglementary to thatstructure shown in Figure Figure 5 is a side elevational view of a pairof companion link-members, partly in section and shown in contractedrelation.

Figure 6 is a side elevational view of a pair of companion link membersshown in extended position.

Figure '7 is a fragmentary sectional view taken substantially on a linel-l of Figure 1.

Referring to the drawing, wherein like numerals designate like parts, itcan be seen that the chain of links is constructed through the medium ofa multiplicity of interconnected companion links generally referred toby numerals 5 and 6. Each of these links is of abbreviated S-shape inconfiguration and each consists-of an outside half shell and an insidehalf shell b.

From each end of each of the inside shells of the links 6 projects aheaded stud I which is disposable into a corresponding keyhole slot 8of-the shell b of the corresponding link 5. Thus the link elements aredetachably connected togetherand their intermediate portions arepivotaiiy connected together by hollow pins 9, and 45 if desiredsuitable spring means can be employed in the link elements and 8 to holdthe assembly in contracted position as shown in Figures 1 and 5, incontrast to the forcefully extended po- 50 sition shown in Figure 6.

As can be seen in Figure 6, the keyhole slot extremities of the linkelements.

extends longitudinally at the end portions of the keyhole slot formedlink elements with the circular openings of the slots disposed inwardlyof the narrow portions thereof, the narrow portions extending outwardlyto terminate adjacent the As is conventional, suitable spring means (notshown) such as the spring 16 in Patent No. 2,225,745 is provided in eachof the complementary linkelements to hold the linkage contracted asshown in Figure 1 of the present drawing. Any longitudinal pull on thelinkage will only serve to hold the studs firmly in the narrow portionsof the keyhole slots and a transverse contraction of the linkage isnecessary to cause movement of any one of the stud carrying linkelements to a position with its studs registering with the circularopenings of the keyhole slots.

when it is desired to break the linkage. the edge portions of thelinkage are pressed inwardly. This action causes movement of aparticular pressed linkelement carrying its stud 'l to a positionregistering with the circular openings of key slots of a complementarylink element, and a slight lateral movement or distortion of the linkageat this point will cause separation of the elements.

While the foregoing specification sets forth the-invention in specificterms, it is to be under stood that numerous changes in the shape, sizeand materials maybe resorted to without depart- 1 ing from the spiritand scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is g A link chainconstruction comprising a lazytong arrangement of pivotal link members.the ends or certain of the link members'being provided with laterallydisposed and headed studs, the ends of complementaryv link" membersbeing formed with keyhole-shaped openings for receiving the headed studsand pivotally connecting the ends of the link members together, thekeyhole-shaped openings in form having a circular opening and a narrowslot extending therefrom, the narrow slots extending from the circularopenings outwardly toward the terminals of the link members and normallyreceiving the neck portions of the headed studs.-
